[0056] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0057] As described in the background technology section, in existing power detection methods, when loading battery cells onto the power detection station, the battery cells are prone to large position deviations. It is difficult to ensure that the probes can align with and contact the grid lines on the battery cells simply by adjusting the position of the probes, thus affecting detection accuracy.

[0058] In view of this, the present application provides a battery cell power detection device. Figure 1 As shown, the cell power detection device in the embodiment of the present application includes a loading conveyor line 1, a first position detection mechanism (not shown in the figure), a loading and handling mechanism 2, a rotating table 3, a second position detection mechanism 4, a power detection mechanism 5 and a unloading and handling mechanism 6, wherein:

[0059] At least one supporting member 31 is disposed on the rotating platform 3 . The rotating platform 3 is configured to drive the supporting member 31 to rotate. A loading station, a power detection station and an unloading station are sequentially disposed on the rotation path of the supporting member 31 .

[0060] The first position detection mechanism includes a first positioning camera, which is located above or below the feeding conveyor line 1. The discharge end of the feeding conveyor line 1 is arranged corresponding to the feeding station.

[0061] The loading conveyor line 1 is configured to convey the battery cell 100, and the first position detection mechanism is configured to obtain the first position information of the battery cell 100 located on the loading conveyor line or the first position information of the battery cell 100 picked up by the loading and transporting mechanism 2. The loading and transporting mechanism 2 is configured to pick up the battery cell 100 from the loading conveyor line 1 and adjust the position of the battery cell 100 according to the first position information, and transport the battery cell 100 to the supporting member 31 located at the loading station. That is, when the loading conveyor line 1 loads and transports the battery cell 100 to the discharge end, or after the loading and transporting mechanism 2 picks up the battery cell 100 from the discharge end of the loading conveyor line 1, the first positioning camera of the first position detection mechanism performs photographic positioning of the battery cell 100, thereby obtaining the first position information of the battery cell 100. After the loading and transporting mechanism 2 adjusts the position of the battery cell 100 according to the first position information of the battery cell 100, it transports the battery cell 100 to the supporting member 31 located at the loading station.

[0062] The second position detection mechanism 4 includes a second positioning camera, which is arranged above or below the supporting member 31 at the loading station, and is configured to obtain the second position information of the battery cell 100 on the supporting member 31 at the loading station. That is, when the battery cell 100 is loaded and transported to the supporting member 31 at the loading station, the second positioning camera of the second position detection mechanism 4 implements the photographic positioning of the battery cell 100, thereby obtaining the second position information of the battery cell 100.

[0063] The power detection mechanism 5 is disposed at the power detection station, and is configured to adjust the position of the detection end of the power detection mechanism 5 according to the second position information of the battery cell 100 to perform power detection on the battery cell 100 on the supporting member 31 located at the power detection station.

[0064] The unloading and transporting mechanism 6 is configured to remove the battery cell 100 that has completed the power test from the supporting member 31 located at the unloading station.

[0065] The cell power detection device of the embodiment of the present application firstly implements the loading and handling of the cell 100 to be detected through the cooperation of the first position detection mechanism and the loading and handling mechanism 2, and implements the position adjustment of the cell 100 during the loading and handling process to ensure that the cell 100 is accurately loaded to the target position on the supporting member 31. Subsequently, through the cooperation of the second position detection mechanism 4 and the power detection mechanism 5, the power detection mechanism 5 implements the power detection of the cell 100 after completing the position adjustment of the detection end.

[0066] It can be seen that the battery cell power detection device of the embodiment of the present application has adjusted the position of the battery cell through the loading and handling mechanism 2 before adjusting the detection end of the detection mechanism 5. In this way, it can be ensured that the detection end of the detection mechanism 5 can be aligned with and contact the grid line on the battery cell 100 after adjustment, thereby ensuring the detection accuracy.

[0067] In order to enable the first positioning camera and the second positioning camera to implement the positioning of the battery cell by taking pictures, optionally, the first positioning camera and the second positioning camera can not only take the image of the battery cell 100, but also have a built-in image recognition module, and the image recognition module has an image analysis algorithm pre-stored therein. When the image analysis algorithm is executed, the image including the battery cell acquired by the first positioning camera and the second positioning camera can be analyzed, so as to identify the battery cell from the image and complete the positioning of the battery cell. Of course, the first positioning camera and the second positioning camera can also be connected to a PLC controller or a host computer, and an image analysis algorithm is pre-stored therein.

[0068] like Figure 3As shown, optionally, the loading and transporting mechanism 2 includes a first UVW adjustment module 21, a linear drive module 22 and a first adsorbent 23, wherein: the linear drive module 22 is connected to the movable part of the first UVW adjustment module 21, and the first adsorbent 23 is connected to the movable part of the linear drive module 22. The linear drive module 22 is configured to drive the first adsorbent 23 to move between the discharge end of the loading conveyor line 1 and the loading station, so that the first adsorbent 23 absorbs the battery cell 100 from the loading conveyor line 1, and places the absorbed battery cell 100 on the supporting member 31 located at the loading station. The first UVW adjustment module 21 is configured to adjust the position of the battery cell 100 according to the first position information after the first adsorbent 23 absorbs the battery cell.

[0069] The linear drive module 22 can adopt various existing linear drive modules that can drive the first adsorption component 23 to move between the discharge end of the feeding conveyor line 1 and the feeding station, such as a synchronous belt drive module, a screw drive module, etc. The first UVW adjustment module 21 can adopt an existing UVW adjustment platform. The UVW adjustment platform is a universal positioning adjustment mechanism, which belongs to a three-axis parallel motion mechanism. It realizes the linear motion of the first adsorption component 23 in the X-axis direction and the Y-axis direction and the rotational motion in the horizontal plane through the parallel motion of three linear moving axes (U axis, V axis, W axis), thereby implementing the position adjustment of the battery cell 100 adsorbed by the first adsorption component 23.

[0070] like Figure 4 As shown, optionally, the power detection mechanism 5 includes a mounting frame 51, a lifting drive unit 52, a first sliding support plate 53, a second sliding support plate 54, a second UVW adjustment module 55, a probe plate 56 and an upper pressing plate (not shown in the figure), wherein: the lifting drive unit 52 is arranged on the mounting frame 51. The first sliding support plate 53 and the second sliding support plate 54 are both slidably connected to the mounting frame 51, and are both transmission-connected to the lifting drive unit 52, and the second sliding support plate 54 is located above the first sliding support plate 53.

The upper pressing plate is arranged on the second sliding support plate 54, and the power detection station is located between the upper pressing plate and the probe plate 56.

[0071] When the cell rotates to the power detection station between the upper pressure plate and the probe plate 56, the second UVW adjustment module 55 is configured to adjust the position of the probe plate 56 according to the second position information of the cell, so that the rows of probes on the probe plate 56 are aligned with the grid lines on the lower surface of the cell. Subsequently, the lifting drive unit 52 is configured to drive the first sliding support plate 53 and the second sliding support plate 54 to slide toward the cell located at the power detection station, so that the rows of probes on the probe plate 56 are pressed against the grid lines on the lower surface of the cell, and the upper pressure plate is pressed against the upper surface of the cell to prevent the cell from being lifted up by the probes and causing a false connection.

[0072] Likewise, the second UVW adjustment module 55 may adopt an existing UVW adjustment platform.

[0073] Optionally, the battery cell power detection device in the embodiment of the present application also includes a detector and a light source arranged above the upper pressing plate, and the upper pressing plate is a plate of a light-transmitting material, for example, the upper pressing plate is a glass plate. The light source is used to illuminate the upper surface of the battery cell pressed by the upper pressing plate and the probe plate, so that the battery cell generates electricity after absorbing the light irradiated by the light source. The detector is electrically connected to the probe to obtain the electrical parameters of the battery cell, and the electrical parameters include the current and voltage generated by the battery cell. The detector finally obtains the power generation power of the battery cell by calculating the current and voltage.

The lifting drive unit 52 includes a first lifting drive member 521 and a second lifting drive member 522, wherein the first lifting drive member 521 is transmission-connected to the first sliding support plate 53, and the second lifting drive member 522 is transmission-connected to the second sliding support plate 54. The first lifting drive member 521 and the second lifting drive member 522 are configured to synchronously drive the first sliding support plate 53 and the second sliding support plate 54 to move closer to or away from each other along the guide rail. Optionally, the first lifting drive member 521 and the second lifting drive member 522 each include two servo motors, and the two servo motors are respectively mounted on two outer sides of the mounting frame 51.

[0075] The first lifting drive member 521 and the second lifting drive member 522 independently drive the first sliding support plate 53 and the second sliding support plate 54 to lift and slide, respectively, to achieve independent lifting control of the upper pressing plate and the probe plate 56, and ultimately ensure that the upper pressing plate and the probe plate 56 can both contact the battery cell, thereby pressing the battery cell 100 from the upper and lower sides. The first lifting drive member 521 and the second lifting drive member 522 can also be driven by cylinders, linear motors, and other drive members.

[0076] Optionally, the supporting member 31 includes a hollow tray and a second adsorbent, wherein: the tray is connected to the rotating table 3. The second adsorbent is arranged on the tray and located in the hollow area of ​​the tray, and the second adsorbent is used to adsorb and carry the battery cell. Since the battery cell is located in the hollow area of ​​the tray, the lower surface thereof exposes the tray, ensuring that the probe plate 56 can contact and press on the grid line on the lower surface of the battery cell from the bottom.

[0077] The second adsorption member may be, for example, a suction cup disposed on the tray.

Four supporting members 31 are provided on the rotating table 3, and the rotating table 3 drives the four supporting members 31 to pass through the loading station, the power detection station, the unloading station and the buffer station in sequence.

[0079] By setting the number of the supporting members 31 provided on the rotating platform 3 to be equal to the number of the stations provided on the rotating path of the supporting members 31, it can be ensured that after each step rotation of the rotating platform 3, there is a supporting member 31 at each station, thereby realizing the synchronous implementation of each operation process and improving the efficiency of the battery cell power detection. Optionally, a detection camera is provided at the buffer station, and the detection camera is used to detect whether there are missed batteries and / or damaged batteries on the supporting member 31.

[0081] By providing the unloading and conveying mechanism 7 and the rotating mechanism 8, the unloading and conveying of the battery cell 100 that has completed the power test is realized, so that the battery cell 100 that has completed the power test is automatically conveyed to the post-processing station. By providing the rotating mechanism 8, the rotation and orientation of the battery cell 100 is realized during the unloading and conveying process, so that the orientation of the battery cell 100 that has completed the power test meets the processing requirements of the post-processing station.
